Dead coin battery

If your C3's keys fob no longer works, the first thing to check is if the battery is dead. Fobs are small coins-shaped batteries that can be replaced in a few minutes.

After cleaning the contacts, you can insert the new battery. Be careful not to mix the two batteries because they differ in their voltages and diameters.

The next step is to examine the battery's voltage. A multimeter set to the battery's voltage range should give you a reliable reading. If the battery shows a voltage that is higher or lower than its threshold, it has to be replaced. You can also start your car using a spare key. However, this may not always work.

Once you do, dry out the circuit board as well as you can using a cotton swab dipped in isopropyl alcohol, or electronic cleaner. If it still doesn't work it could be time for a new key fob.

Signal interference is a common reason for Citroen remote controls not working. This could happen when there is an intense electrical field near the vehicle or from other transmitters on the same frequency. Once you have left the interference area your key fob should be working normally again.

Finally, the Citroen c3 key fob can cease to function due to worn buttons or signal interference, receiver module issues, a dead 12 volt battery, or a defective electronic chip. If this happens, you'll probably require it to be replaced by a skilled technician. This can be accomplished by a qualified mechanic or an Citroen dealer. If the issue is significant then you'll have to get it replaced. This is a simple and cost-effective fix, however it's crucial to act fast. The longer you delay to address the issue, the more deteriorated it becomes. It could be dangerous for passengers and yourself in the event that the issue isn't addressed.

Receiver module issue

If your key fob stops working, it might be due to the receiver module having developed a fault. Water damage is one of the many causes. This can happen when you accidentally drop your keys or wash them. You can try to fix the problem by removing and cleaning the chip with isopropyl alcohol, or electronic cleaner. This will keep the chip from getting corroded.

You can also reset the receiver module by disconnecting it from the car battery and then waiting for 10 minutes. Then, reconnect the battery and repeat the process. If this isn't enough to fix the issue, you can take it to a dealer to have it replaced.

Interference can cause your key to stop working. It can be caused by other transmitters on the same frequency or objects inside your vehicle. If you're unable to fix the issue, go to a dealership to change the key fob's programming.

The key fob contains a short-range radio transmitter/radio-frequency identification (RFID) chip and antenna, which sends a distinct coded signal to the receiver module in your car. If the signal isn't in order, the receiver module will not recognize the key and display a message that says "Key Not Detected. This can be a frustrating issue particularly when trying to start your car.

Dead 12 volt battery

If your key fob stops working after a battery change the device could be damaged. This is especially common when the key fob is dropped or stepped upon, but it can also happen following servicing on your car that requires removal and reinstallation of the panels.

Another possibility is that the fob is getting interference from other devices or places. This could cause the RF signals to weaken, preventing the car from being able to recognize the remote. It is possible to reset the onboard computer in this situation, by disconnecting the 12-volt battery for 15 minutes. This will remove any residual electrical energy, allowing the system to reboot.

It is crucial to determine the size and type of the battery before replacing it. If the battery you replace isn't big enough or has an incompatible voltage, it could damage the circuit board within the fob's key. You should also remove any corrosive materials off the chip inside the fob before installing the new battery. The correct battery type will ensure that the key fob is sealed and shielded from moisture. Once the key fob has been reinstalled it should function normally. In the majority of cases, you can use the second key to start your vehicle even if it shows an error message that reads "key not found."
